In Windows 10, if you have your display settings set to scale the fonts and gui to anything higher than 100% the mouse pointer in PCem goes wonky. I'm guessing it is moving faster in coloration to your scaling factor. I noticed this as I now have a 3440x1440 monitor, and prefer to set my scaling to 125%.

To reproduce, right click on host desktop, and chose display settings, in Scale and Layout, set higher than 100%. Launch a Windows 98 session in PCem, and the mouse is now unusable.

Also, grabbing the bottom right corner of the PCem window to resize it using a high resolution display is next to impossible, hence my previous suggestion of adding a status bar with resizing corner at the bottom of the PCem screen.

I use 175% scaling with a 1920x1080 resolution. The bottom of the configuration and hard disk windows get completely cut (which means that the OK and Cancel buttons aren't visible/are off the screen).

It's unfortunate that the PCem development doesn't seem to focus more on improving the GUI and fixing its bugs. To be honest I really love PCem and it's concept and would love to use it instead of VMWare Workstation or DOSBox, but it's unusable to me due to all these problems that I've reported many times and remain version after version.

I have the same problem. I have a high resolution display and the default setting of scaling is 150%. If I set it to 100% everything is too small. But if I set it to 150% the mouse in PCem is not usable. I hope this problem can be solved soon.

I'm on Windows but I don't have a build system setup. If you wanted to share either a compiled executable or your build system with me, I'll build it. It seems there are a lot of steps to get all of the dependencies to even build the project. I'm just having a hard time making time to do that.
